Division of Public Health Immunization Information 

The Delaware Immunization Information System (DelVAX) accepts immunization data — directly reporting (update) or query — from Electronic Health Record (EHR) systems through a real-time bi-directional web service interface, using Health Level 7 (HL7) messages formatted in version 2.5.1.

DHIN and the Delaware Immunization Program have worked closely to develop an immunization reporting/query web service to assist facilities’ and EHR vendors’ connections with DelVAX.

Please follow this link for the DelVAX Implementation Guide, Facility Code Request Form, Add/Delete Provider Form and HTTP Post Soap Forwarder guide: http://dhss.delaware.gov/dhss/dph/dpc/immunize-providers.html.

You may also contact the DelVAX onboarding team of Cheryl Oliver-Knight (cheryl.oliver-knight@state.de.us) or Fred Bailey (fred.bailey@state.de.us) for more information.

If you have questions relating to the Public Health’s Cancer Registry, Newborn Screening Program, Syndromic Surveillance and Meaningful Use, please visit the Delaware Division of Public Health website.
